Overview

Challenges in Rail Condition Measurement 

• Continuous Issues
  – Rail wear, deformation, and defects accelerate with axle load, speed, curvature, and gradient.

• Need for Precision
  – High-precision continuous inspection is required.

• Operational Difficulty
  – Reference point shifts from deformation hinder on-line inspections.

• Manual Limitations
  – Manual devices show low reliability, operator variability, and poor precision.

• High Costs
  – Imported equipment causes high purchase and maintenance expenses.
